High-performance electromagnetic shielding assemblies

A wireless communication electronic assembly can include a plurality of integrated modules each having a ground plate interfaced to each other and defining a shielding plane. Each ground plate can have a left edge and a right edge opposite each other. A plurality of wireless communication devices can be positioned on one side of the shielding plane, and a plurality of electronic devices can be positioned on the other side of the shielding plane. One or more electromagnetic shielding elements, such as gasket(s), channel strip(s), stamping element(s), etc. can be disposed between the left edge and the right edge of adjacent ground plates to electromagnetically shield the plurality of electronic devices from the plurality of wireless communication devices. The left and right edges can be recessed or offset on one side of the shielding plane. Rows and columns of integrated modules can be interfaced about a plurality of electromagnetic shielding elements. A method of installing and replacing integrated modules of an antenna array.
